The EXO2278 Losi Nascar Aluminum Lightweight Drive Shaft is a precision-engineered upgrade driveshaft designed specifically for Losi NASCAR series RC cars. Crafted from hard-anodized 7075 aluminum, this lightweight driveshaft significantly reduces rotational mass compared with the stock steel unit, weighing approximately only 7 g versus about 22 g for the original. The reduced weight allows the motor to spin more freely, resulting in higher RPMs, quicker acceleration, and reduced drivetrain heat during intense racing sessions.
The driveshaft features a rounded middle section that trims excess weight while maintaining strength and rigidity. Precision machining ensures smooth power transfer from the transmission to the wheels with minimal driveline lash, improving overall responsiveness and performance on the track. The wear-resistant aluminum construction also enhances durability and longevity, making it an excellent choice for competitive racers or performance-minded hobbyists.
